Sulfhydryl compounds in the treatment of cystinuria

open access: yesWorld Journal Of Urology, 1986
Cystinuria, an inborn error of metabolism, is clinically characterized by the formation of l-cystine crystals and stones in the urinary tract. Sulfhydryl compounds react with the less soluble cystine to form water-soluble disulfide derivatives. l-Cystine stone formation and its undesirable side effects are thus prevented, and regulation of its ...
